Ever since you became a Hashira and met Muichiro, you both became quite close. Having similiar interests, and being around the same age as him. He was mostly cold to everyone else, but when it came to you he was calmer but still neutral about things.

You both didn't have a mission to go on. And currently, you were brushing and styling his hair to however you please. Muichiro looked very bored, his eyes narrowed as he stuck his tongue out and blew a small raspberry.

Muichiro: "I don't understand why you like doing my hair."
